LAS VEGAS — Remember the Hammerhead? It’s a device that attaches to your bicycle, links to the GPS on your phone via Bluetooth, and guides you along a pre-chosen route by flashing a left or right light when you need to turn.

Schwinn‘s new CycleNav does one better. Like the Hammerhead, it attaches to your bike (via quick release) and flashes an LED light to alert you to an upcoming turn. But it also speaks voice-guided turn-by-turn navigation to you through a speaker, just like your iPhone does.
